Here's how

Step 1

Choose a suitable area large enough to accommodate a 2.86m-dia circle, plus enough space for any surrounding plants. Remove lawn and weeds. Decide on centre of circle, drive in stake and tie stringline around. Measure out 1.43m, then tie other end of stringline around set-out paint can. With stringline taut, walk around space to draw circle.

Step 2

Lay aluminium edging according to manufacturer’s instructions. Excavate within circle to depth of 100mm and use rake to remove roots.
